Patented Sept. 15, 1931 ingaat? Partnr carica CHARLES I-I. SUCKEL, OF JACKSON HEIGHTS, NEW YORK AU'IOllrIl-LTIC SASH FASTENER Application led October 14, 1929.

One of the primary objects of my invention l is to provide a fastener which will automatically lock the sashes together, when the same are moved to their extreme closed position, thereby insuring of the effective locking of the window without any attention to the fastener on the part of the operator.

Another important object of my invention is to provide a sash fastener which is so constructed that the upper and lower sashes will be drawn into intimate contact with one another and held against rattling when the sashes are removed to their eXtreme closed positions.

A further object of my invention is to provide an automatic window sash fastener which can not be picked from the outside of.

the window by the insertion of an instrument between the meeting rails of the sashes or shaken loose by manipulating of the sashes.

A further object of my invention is the provision of an automatic window sash fastener embodying a spring pressed locking bolt normally held in a retracted unlocked position by a gravity ball, and a combined keeper and strike plate for engaging and moving the ball to a raised position for permitting the lock bolt to automatically move to a locked position in engagement with said combined keeper and strike plate.

A further object of my invention is to provide an improved window fastener of the above character, which will be durable and efficient in use, one that will be simple and easy to manufacture, and one which can be laced upon the market at a reasonable cost. lVith these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawings, in which drawings Figure 1 is a top plan view of my improved sash fastener showing the same in its looked position and applied to the meeting rails of a pair of window sashes.

Figure 2 is a section through the Same Serial No. 399,554.

taken on the line 2-2 of Figure 1 looking Y i in the direction of the arrows showingthe locking bolt in its locked position.

Figure 3 is a vieu' similar to Figure 2 showing the locking bolt in its retractedposition for permitting the separation of the sashes.

Figure 4 is a view similar to Figure 3 showing the meeting rails of the sashes separated and illustrating the position of the gravity ball for holding the bolt in its retracted unlocked position. l

Figure 5 is a detail perspective view of one section of the improved fastener showing the clamp plate thereof separated from the body portion thereof, and

Figure 6 is a perspective-view of the combined keeper and strike plate. e

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A generally indicates my improved sash fastener and C and B the upper and lower sashes of a Window with which the fastener is associated.

The sashes B and C can be of any preferred or ordinary construction and as shown inplude the meeting rails 10 and 11 respective- The improved fastener A comprises the body or casing 15 'for the locking bolt or shaft 16 and, as shown, the body or casing 15 is provided with a longitudinal bore for receiving said bolt. The bore is enlarged as at 17 and opens out through the rear end of the body or casing for the reception of an expansion spring -18 which yis placed about the said bolt. The spring is retained in position in the enlarged portion 17 of the bore by means of a closure plug 19 which is threaded in said bore and one end of the spring abuts against the same. This closure plug is provided with an axial opening through which the bolt slidably extends and this end of the bolt is provided with a manipulating thumb piece 20.

A cross pin 21, collar or the like is secured to the bolt 1G and the forward endof the spring normally bears against this ypin and functions to urge the bolt normally out of the casing or body as clearly shown in Figure 2 of the drawings. The casing or body l5 is provided with laterally extending ears 22 whereby the body or casing may be secured to the top face of the rail l0 by the use of suitable fastening elements 23.

The front face of the body or casing is provided-with a substantially verticalsemicylindrical groovef24 which terminates short of the bottom of the body or casing and this groove is adapted to slidably receive a gravity ball or similar member 25 fora purpose` which will be later described. The upper inner edge of the body or casing l'hasse; cured thereto a clamp plate 26 which projects over said groove and this clamp plate 26" includes a :substantial horizontally disposed attaching,v plate portionf'27 i and Ia.-depending substantially'v 'vertically disposed: plate p or.L tion'f28f i Theinner face-ofv -the-verticalplate por-tion? 28s-is inclined upwardly andinwsard ly; asfvindicated by` thel reference f character 129 fer a-.qpurpose` which? will-.also be hereinafter more fully described; v
